Hi,

I'm trying to clean out my wifes, PC, she unfortunately let a visiting child loose on it for 10 minutes and have been getting all sorts of strange and offensive popups since, any help gratefully accepted. I have run both Spybot and Ad-aware before running HijackThis.
Thanks
Mark

Click Fix Checked

Then download LSP Fix from here. Only remove what I instruct you to remove, removing anything else could cause problems with your internet connection:

1. Run LSP Fix by double clicking the file you downloaded
2. Put a checkmark in the I know what I am doing box
3. Remove all entries of nutafun4.dll in the Keep column by clicking the entry and pressing the Arrows to put it in the Remove Column. If the entry is already in the remove column, ignore this step.
4. Click Finish

Then boot into Safe Mode and ensure that you are showing Hidden Files and Folders.

Go to Start> Control Panel and uninstall the following:
Web_Rebates

Delete the following files and folders:
C:\WINNT\system32\exrfdtk.exe
C:\Program Files\Web_Rebates

Reboot and post a fresh log

Thanks for the advice, I've run all the actions suggested and it does seem better.

Here's the latest log.

Thanks again

Thats a clean log, how are things running?

(Don't bother about the file, just a let over entry)

The wife reports it is running a lot better, I'll keep on top of the regular scans.

Many thanks for your help.

Cheers
Mark

Have a read of this info to Prevent It Returning:

Preventing it returning

After your problem has been resolved on the forum, it is an absoulute MUST to do the following steps to prevent the problem returning. Click on the link to get access to the software or webpage that I'm referring to.

1. Visit Windows Update
Pay a visit to Windows Update and scan for and download ALL Critical Updates and Service Packs. New updates are usually released monthly so check back to Windows Update every month.

2. Download Antivirus Software-
If you haven't already got Antivirus software, you should download and install AVG Antivirus. It is freeware and is updated nearly every 2 days (sometimes more frequently if there are a lot of new viruses) and in my opinion, is better than some Antivirus software such as Norton. Antivirus software will prevent viruses infecting your system and it is important that you update it every two days or every week at the most.

3. Download a Firewall-
If you haven't already got a firewall, it is Very important that you download one. Firewalls will prevent unauthorised access to your computer and stop data leaking out of your computer. You may think that it won't happen to you, but Hackers don't care who you are, what you do, where you live or what you had for tea last Sunday on your holiday in the Lake District, they want your data. Firewalls will keep these sneaks out and one of the best is Sygate Personal Firewall, which happens to be freeware.

4. Spyware Scanners-
It is important that as well as having real time spyware protection, you have a spyware scanning application. If you have not already been told to download one earlier in this thread, it is a good idea to download Spybot Search And Destroy and Ad-aware. They are both spyware scanners and will search for a remove spyware. It is recommended that you have both, because one will pick up entries that the other misses. It is even a good idea to download these if you have other programs such as ASE, Spysweeper, Pest Patrol, etc, because one spyware scanner will not pick up everything. Please remember to update your spyware scanners weekly/fortnightly.

5. Prevent Spyware slipping through Internet Explorer-
